Abstract
- Purpose: The authors conducted a retrospective, multicenter study to investigate the differences in the fixation patterns, in terms of number and thickness of plates, between patients in whom a third molar (3M) was maintained or removed in the line of mandibular angle fractures.<br />Materials and Methods: The study was conducted in 6 European level I and II maxillofacial trauma centers. Data were collected on patients ≥ 16 years of age who underwent open reduction internal fixation (ORIF) for mandibular angle fractures (MAF) from 2008 to 2018, in whom a 3M in the fracture line was present and who had a follow-up duration of 6 months. The study population was divided into 2 groups: patients treated with ORIF in whom the 3M was maintained (group 1) and those treated with ORIF in whom the 3M was extracted (group 2) during treatment. The 2 groups were compared for differences in the internal fixation pattern, specifically in terms of the number and thickness of the plates.<br />Results: A total of 749 patients with 774 MAF were collected. A total of 1,050 plates were placed: 849 were ≤ 1.4 mm thick (80.9%) and 201 plates ≥ 1.5 mm thick (19.1%). 548 patients were treated with ORIF and 3M maintained (group 1), and 201 treated with ORIF and 3M extracted (group 2). Statistically significant differences were seen in the number of ≤1.4 mm plates between the 2 groups for single undisplaced/displaced MAF(P value ≤ 0.5) and for undisplaced/displaced angle + parasymphysis/body fractures (P-value ≤ 0.5).<br />Conclusions: Analyses of data collected from 6 European maxillofacial centers indicated that the majority of surgeons of our sample perceived the MAF as being more unstable when removing the 3M during ORIF leading them to perform a rigid fixation in the angular region.<br /> (Copyright © 2020 American Association of Oral and Maxillofacial Surgeons.
